According to Matt Barrows of the Sacramento Bee, quarterbacks Alex Smith, David Carr and Colin Kaepernick were joined by only three receivers, Kyle Williams, Kevin Jurovich and an unknown pass catcher from San Jose State, giving the passers a one-to-one ratio with the receivers. A training-camp ratio would be three to one in favor of receivers, who do more running, and are therefore more susceptible to tweaks and muscle pulls, than any other position group, the wideouts in Tuesday’s session were understandably worn out when it ended.
Kaepernick took some warm-up throws and made some passes at the beginning of the session but gave most of the practice throws to Smith and Carr. Kaepernick is not yet fully recovered from a minor surgical procedure to his lower left leg that he had after the draft. Michael Crabtree, meanwhile, recently has been working out on his own in the Bay Area, but he has yet to join the group of 49ers that works out together.
